I assume that invisible picture is the Bard.
Hm, don't know what happened there. When I posted it, it was not only visible but downright enormous. Indeed sometimes when I look at your post, Mary, it's enormous there as well. And then sometimes he disappears. Analogous in a way to the sense of authorial presence itself in the Bard's work, I suppose. But somehow much more annoying.
I've replaced it with a slightly less enormous but hopefully more stable Bard.
A, the way I see it (just me personally although a few of us seem to be playing it a bit this way) is that the number is the destination and I try to think of an interesting way to get there. So if some great event happened that year then wonderful, even better if there's a picture of that event with the year on it. But after there have been too many of those then that gets a bit boring so something from the auction site brings welcome relief. Or even just something mathematical about the number.
It's a bit like Mornington Crescent.
Oo look, bus 1584 being driven by Satan.
